[squeak-dev] Debian tarball updates?

OK.  The reason I ask is I'm a bit concerned that the Debian maintainers
might push back on, or even reject, a combined VM package as it would
likely be harder to follow from a package organization standpoint and
therefore more difficult for them to maintain.  If the main objective is
that we have a unified launch script, we could do that pretty easily with
multiple packages: one for the classic VM, one for the stack/cog/spur VM
and one for the launcher script (which could be a dependency of both VMs
and therefore automatically installed.)  The launcher script could then
detect which VM(s) are installed and either launch the appropriate one or,
if it is not available, suggest the user install it.  Would that be an
acceptable approach or would you prefer to pursue a single unified package?

Whichever way we proceed, contact should probably be made with the Debian
maintainers to at least let them know a significant change is coming and
see if they have any feedback that needs to be taken into consideration.
Does the Board already have someone who would handle that or would you like
me to?

On a related note, I've been busy dusting off my packaging knowledge: over
the weekend I managed to get a package-based VM to build manually using a
skeleton package.  Still a fair amount to do before I'd call it 'usable',
but it did confirm that the basic build part of the equation shouldn't be a
big deal which I was hoping would be the case.

P.S. Oh wow!  Just looked at the http://files.squeak.org/debian/ link...
people should definitely be steered away from using that unless they have a
specific reason to still use that.  The package already in the Debian repos
is definitely more current and usable (for older images) on recent Debian
releases... there are only a handful of patches they've applied.  Should I
forward them to Dave for review?
